Introduction In the past, several experimental studies have been performed to define the operation scenario in case of EC assisted start-up, especially in view of ITER[1]. ECRH has been demonstrated to successfully sustain the burn-through of pre-filling gas and impurity coming from the wall. Anyway, a complete database in presence of controlled impurity puffing in the prefill phase that mimics not favourable post-pulse conditions (such as would be expected after disruption event), does not exist yet (for a low applied toroidal electric field as will be used in superconductive machine).
